Jim Carrey has a new place to try out his comic material -- the nursery. The 47-year-old actor is now a grandfather.

Carrey's daughter Jane, 22, gave birth to her first baby -- a son named Jackson Riley Santana -- early Friday morning, according to a media release.

The child was born in an unnamed Los Angeles hospital weighing 7 pounds and 11 ounces.

Besides the first name of "Jackson" the boy will have some serious musical advantages Jane is a singer-songwriter for the alt-rock The Jane Carrey Band and the father is Alex Santana, the lead singer of the metal band Blood Money. The two were married in November.
